Sea Surge risk & flood impact assessment in the Coastal Area of Southern Gaza Strip (Occupied Palestinian Territory) as of 29 August 2025

**UNOSAT code: FL20250828PSE** This map illustrates the current shoreline and the highest observed watermark in the Gaza Strip (Occupied Palestinian Territory), derived from Sentinel-2 and Pleiades imagery acquired on 28 July 2025 and 29 August 2025, respectively. The analysis focuses on the area west of Al Rashid Road, where a very high density of tents has been observed within a small geographic area that is particularly prone to flooding in the event of high tides or storm surges. UNITAR- UNOSAT has identified 350 internally displaced persons (IDPs) in high-risk areas (within 20 meters of the highest observed watermark) and 1,252 IDPs in risk areas (within 50 meters of the highest observed watermark). This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).

**UNOSAT code CE20231007PS** UNOSAT's satellite-detected damage and destruction to buildings within the area of interest in the Gaza Governorate, Gaza Strip, based on an image collected on 15 October 2023 compared to an image collected on 10 October 2023 (partially clouded), and 10 May 2023 shows a total of 533 destroyed structures, 640 severely damaged structures, and 1273 moderately damaged structures, for a total of 2246 affected buildings as of 15 October 2023.
